Flaps were elevated bilaterally, the premolars hemi\u2010sectioned and the distal roots removed. The implants were placed in contact with either the buccal (test site) or with the lingual (control site) bony wall of the extraction sockets. Healing abutments were affixed and triangular buccal bony dehiscence defects, about 2.7\u00a0mm deep and 3.5\u00a0mm wide, were then prepared. No regenerative procedures were done and a non\u2010submerged healing was allowed. After 4\u00a0months of healing, block sections of the implant sites were obtained for histological processing and peri\u2010implant tissue assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After 4\u00a0months of healing, the bony crest and the coronal border of osseointegration at the test sites were located 1.71\u00a0\u00b1\u00a01.20 and 2.50\u00a0\u00b1\u00a01.21\u00a0mm apically to the implant shoulder, respectively.
